There are two people whom Edward and Alphonse fear most, and they are caught with those masters of alchemy in the Rush Valley. They know that Edward has become a State Alchemist, and in anger grabs the two brothers and takes them to... Meanwhile, Colonel Mustang has been formally reassigned to Central City.

Ed and Al have been tracked down by their former master. She is angry that her apprentices went against her teachings and degraded themselves by becoming dogs of the military.

Back at Eastern headquarters, Mustang has officially received his transfer orders to start work in Central City. As a farewell gift, Mustangs requests that he be allowed to take along some of his subordinates. His request is approved.

On a train headed back to Dublith, Ed and Al are tied together while their teachers sit in a diner eating. Winry is surprised that their teacher is so beautiful, but Ed tells her that they have met before. They officially became her apprentices at Resembool.

Realizing that studying on their own had its limits, the brothers decide to seek a teacher. That night, there is a heavy rain that may collapse the river banks. The two head out to help and using their alchemy they seek to repair the leak in the sandbag dam. It is here that they witness the power of a woman who, using no transmutation circle, constructs a barrier that saves the river bank.

Impressed by her skills, Ed and Al beg to become her apprentices. She asks to borrow the two for trial training to see if they are worth being taught alchemy and if they have the talent.

All around the East, many of Mustang's subordinates are receiving phone calls. Assembling in his office, Mustang informs the five members that they will be transferred to Central City with him.

Finally arriving in Dublith, Ed and Al get the chills when they think of what will happen to them. Watching Izumi-sensei, the brothers learn an important lesson. They should fix whatever they can with their own hands instead of relying on alchemy.

After fixing a toy train for a group of boys, Manny comes running to her say that Chico is in trouble. The cat is on the roof with a dog barking from below. Ed scales the wall and see that Chico has given birth to a litter of kittens but has lost her life in the process.

Suddenly, a kitten slips and tumbles off the roof, but Ed saves it using alchemy. Saddened by Chico's death, Manny is told by Izumi-sensei that everything in this world flows in a continuous circle.

Alone with Izumi-sensei, Ed and Al face their teacher once again. Realizing that Al's armor body is empty and Ed's arm and leg are made of auto mail, she asks if Ed and Al have seen "it". She asks to hear what happened, and Ed explains that they transmutated their mother.
